Unknown rubber hose on rear of Mariner 55

[jonathan@comstar.co.uk]

Hi,<br /><br />I bought two Mariner 55s recently and have now setup the engines. However, there is a rubber hose on the back of the engines and I was wondering what this is for? The hose rises from just above the anti cavitation plate and is about 8-10 inches long. It has a metal end with a screw plug in it. This metal end is formed to obviously allow some other hose to be fitted over it and be held in place. I wondered what this hose is for. Can anyone tell me?<br /><br />Thanks,<br /><br />Jonathan

These are built in speedometer sending units. Keeps you from having to attach one to the transom. Use them or not, your choice.
